  • the socket configuration on one side of the separator plate can comprise a plurality of like units separably and complementarily fitted to one another in front-to-back relationship.
  • This invention relates to a socket for relays.
  • Prior art relay sockets have normally been provided with a predetermined number of poles i.e., such that they are for double-pole .or triple-pole use, and have not been allowed to be divided. It has therefore been required to use, eg for a triple-pole relay, a triple-pole socket. For this reason, stock management has been troublesome.
  • the socket of the present invention permits connection leads to be inserted from one side of each socket unit, whereby wiring becomes much easier.
  • the present invention provides an end plate which is positioned internally in the assembled relay socket.
  • One or more first socket units each of which has an open front side, are assembled in front-to-back relationship; the open front of the forwardmost unit is then covered by an end plate which acts as a separator plate; and the unit is completed by then adding a second socket unit symmetrical to the aforementioned first units but having its open face disposed in the opposite direction, on the side of said separator plate opposite to, and in front-tofront relation to said first units.
  • An object of this invention is to provide, in a socket having a rectangular base at the central part thereof, terminal-inserting openings for a relay which are formed in the upper side of said base, and lead-out terminal mounts from said terminal-inserting openings which are disposed in a stepped fashion at both ends of said base.
